AAdd the network 192.168.40.0/24 to the masterAuthorizedNetworksConfig. Configure kubectl to communicate with the endpoint 192.168.38.2.

BAdd the network 192.168.38.0/28 to the masterAuthorizedNetworksConfig. Configure kubectl to communicate with the endpoint 192.168.38.2

CAdd the network 192.168.36.0/24 to the masterAuthorizedNetworksConfig. Configure kubectl to communicate with the endpoint 192.168.38.2

Wait, are we sure about the endpoint IP? That seems off!

D? Really? Why add an external IP when it's unnecessary?

C doesn't fit the subnet, so it's a no-go.

I think B is better, smaller range is safer!

Option A seems right, matches the subnet.

I feel like adding an external IP to the VM could be a valid approach, but I’m not sure if that’s necessary in this case.

I practiced a similar question where we had to configure kubectl access, but I can't recall if we needed to add an external IP or not.

I think option A sounds familiar because it mentions the same subnet as the VM, but I’m not completely confident about the subnet mask.

I remember something about masterAuthorizedNetworksConfig, but I'm not sure which IP range to use. Was it the one from the VM or something else?

I'm not totally sure about this one. I'll need to play around with the different regex options to see which one best matches the criteria of prices 100 or greater.

I'm a bit confused on this one. Accessing data in @TestVisible class variables seems like it could be a valid option, but I'm not sure if that's the best approach. I'll have to think about this one a bit more.

I think the key here is to find a DiffServ technology that can provide backward compatibility with the current IP Precedence solution. Based on the question, I'd go with option C - class selector code points.
